ultrasonic sensor

Ultrasonic gas flowmeters are widely adopted in industrial applications due to their advantageous features, such as zero pressure loss and easy installation. However, the conventional threshold detection method, despite its real-time performance, suffers from degraded accuracy caused by circuit and pipeline noise, which introduces fluctuations in echo signal amplitude and phase. This paper theoretically demonstrates that doubling the ultrasonic signal frequency steepens the rising edge slope of the echo signal, reducing the time interval during which random noise affects comparator output.

Ultrasonic flowmeters that use transit-time ultrasonic transducers face measurement errors due to ``crosstalk,'' whereby the working signal travels through the pipe wall and couplings, interfering with the signal from the fluid.  Although various procedures have been proposed to solve the issue of crosstalk, they're limited to low-frequency ranges, or they are not effective in high-pressure environments.
